Application Scenarios & Design Considerations

3-Pin Switch-Mode LED Lamp Driver ICs

Alternative Part Number

  • AL9910-5S-13 --: Buck LED driver IC with wide input voltage range and internal MOSFET, functionally similar to the HV9922 offline LED driver in a small SO package.
  • BP3105 --: Offline constant-current LED driver IC with integrated high-voltage MOSFET, commonly used as a cost-effective substitute for Supertex HV99xx LED drivers.
  • MP4021 --: Non-isolated offline LED driver controller with high-voltage startup, suitable replacement for HV9922 in low-power LED lamp applications.
